Revitalizing a Concrete Pond: Our Membrane Installation Process
At Neo Roofing Solutions, we understand that every project, big or small, deserves meticulous attention to detail. Recently, we completed a specialized membrane installation for a concrete pond that significantly enhances its durability and longevity. While this pond isn’t situated over any living space, we approached the task with the same commitment to quality as we would for any roofing project. Let’s walk through the steps we took to ensure a successful installation.
Step 1: Preparing the Surface
Preparation is key to any successful installation. In this case, the concrete for the pond was poured 28 days prior to our work, allowing it to cure adequately. Before starting, we pressure washed the entire surface to remove dust, debris, and any contaminants that could interfere with the adhesion of the membrane. The following day, we returned to find the surface completely dry. To ensure it was fully ready for primer, we performed a final vacuum sweep, confirming that the surface was clean and primed for the next steps.
Step 2: Applying the Bituminous Primer
With the surface prepared, we proceeded to apply the Elasticol 500 bituminous primer across the entire pond surface. This primer is essential for promoting strong adhesion between the concrete and the membrane layers that would follow. A solid foundation is critical to the long-term performance of the roofing system, and this primer is designed to enhance that bond.
Step 3: Installing the First Ply
Our system consists of a two-ply membrane installation, starting with the Sopralene Flam 180. This product was meticulously applied to the bottom of the pond, ensuring thorough coverage. It was crucial to terminate the Sopralene Flam 180 at a safe distance from all drains and pipe protrusions to avoid any risk of melting the plastic with torch heat. After laying the first ply, we heat-welded it securely to all curbs and walls, ensuring a robust and watertight seal.
Step 4: Installing the Second Ply
Next, we moved on to the second ply, using Sopralene Flam 250 GR. This layer was also torched down, with seams carefully offset from those of the base ply to prevent potential weak points in the membrane. Again, we maintained a safe distance from all protrusions, following best practices to ensure durability and reliability. The Sopralene Flam 250 GR was heat welded along all curbs, ensuring a seamless integration with the first layer.
Step 5: Flashing and Finishing Touches
To ensure maximum protection around all drains and pipe protrusions, we installed patches of Alsan 230 Flash—fully reinforced with resin-fleece-resin. This patch extends 4 inches onto the completed SBS (styrene-butadiene-styrene) membrane and wraps around the pipes and drains, creating a secure barrier against leaks.
Around the perimeter of the pond, we applied a 4-inch strip of Alsan 230 Flash onto the iron curb, providing an additional layer of protection. To finish, we coated the Alsan 230 Flash with Alsan 287 Color Coat in black, giving the installation a polished and professional appearance.
